- 4. Multiple Choice
Car A is traveling to the right with a speed of 29m/s when the rider slams on the accelerator to pass car B. Car A passes car B in 110 m with constant acceleration and reaches a speed of 34m/s. We want to find the acceleration of the car as it speeds up. What equation should you choose?
vf=vi+at
Δx=vit+1/2at2
vf2=vi2+2aΔX
Δx=((vf+vi)/2)t
